I finished off doing the rear brakes today on my 2006 XC70..... read a few stories on here about guys doing the whole job in 1 1/2 hours, I would love to have these guys as my mechanic
As a very much amateur mechanic, it took me near 4 hours on one side and 2.5 hours on the other
Anyway, I bought a set of OEM discs and pads from partsforvolvos.com who had the set on a special for £108. I bought a set of Shoes, springs and adjusters on ebay, these are Bremtech and found the link on here for these.

I didn't have a 7mm allen head socket so I cut a piece off an old 7mm caliper key in my tool box which worked a treat on the sliders. Stripping down was relatively easy, getting the disc off the shoes needed some hammer coaxing as a ridge had formed in the bore.
The shoes on the NS had completely gone with only a few delaminated pieces still in the disc bore (drum). The OS had even wear but little left.
Fiddliest jobs for me were removing and fitting the centre springs and refitting the bottom shoe by dragging down on the larger side spring, this needs to fit on the inside on the cable linkage. I also had an issue re fitting the new discs over the new shoes. I loosened the handbrake cable off fully before starting of course but still very tight on the NS and impossible on the OS.
Because I was replacing the H Plate Spacers with adjusters, I measured the slot gap between to 2 slots on both the plate and the adjuster, exactly the same when fully closed (adjuster). I filed a nice chamfer over the leading edge of the new shoes, still no go..... I checked that the shoes were as fully closed at they can be at both ends.... they were indeed. Hit on an idea to remove the adjuster and grind material from both faces (screw slot and pin slot ends of the main body), trial and error got me to a reduction of 4mm between the slot faces was just enough to allow the shoes to close just a little more allowing the disc to tightly slide over.... result!!
I will let these new shoes bed in for a few weeks then I can adjust to take up any slack. You could do this mod with the H spacer plate as well by filing down the faces of the slots to reduce each side, but with the adjusters its obviously got the ability to take up future slack
I found the OS more difficult that the NS, put that down to being right handed to getting at things maybe a bit trickier.
